Scientists said on Thursday that coral growth in Australia's Great Barrier Reef has fallen to its lowest rate for 400 years, in a troubling sign for the world's oceans. Glen De'ath and colleagues at the Australian Institute of Marine Science believe the slow growth could threaten a variety of marine ecosystems that rely on the reef and signal similar problems for other similar organisms worldwide. The Great Barrier Reef is the largest coral bed in the world, composed of over 2,900 individual...

Scientists at the New York-based Wildlife Conservation Society (WCS) report a rapid recovery in coral reefs off the coast of Indonesia damaged by the 2004 Asian tsunami. Some had feared the reefs might take a decade to recover. However, the WCS team found evidence of fast growth of young corals in some badly hit areas in the Indian Ocean.  A WCS spokesman reported that reefs damaged prior to the tsunami were also recovering. Some communities are foregoing destructive fishing techniques...

Scientists say they're gaining insight into climate change from rapidly recovering tsunami-damaged coral reefs in the Indian Ocean. Even some reefs badly damaged four years ago in a massive tsunami are showing a rapid growth of young coral, said the Wildlife Conservation Society in New York. This is a great story of ecosystem resilience and recovery, said Stuart Campbell, a spokesman for the society's Indonesia marine program. The recovery has been aided by communities that have abandoned...

The remainder of the world's coral is in danger of being eliminated as a result of human activities, pollution and over-fishing, according to an international report. Released on Wednesday, the "Status of Coral Reefs of the World: 2008" found that one fifth of the Earth's coral reefs have disappeared since 1950, and the remainder could die off over the next 20 to 40 years unless initiatives to curb greenhouse gas emissions are enforced. "Climate change must be limited to the absolute minimum...

What began as an homage to achievement in the field of coral reef geology has evolved into the discovery of an unexpected link between corals of the Pacific and Atlantic. Dr. Ann F. Budd from the University of Iowa and Dr. Donald McNeill of the University of Miami named a new species of fossil coral found on the Island of Curaçao "“ some six million years old "“ after renowned coral reef geologist and University of Miami Rosenstiel School professor, Dr. Robert...

We've all seen the satellite images of Earth at night--the bright blobs and shining webs that tell the story of humanity's endless sprawl. These pictures are no longer just symbols of human impact, however, but can be used to objectively measure it, according to a study in the December 2008 issue of Geocarto International, a peer-reviewed journal on geoscience and remote sensing. Travis Longcore, a USC geographer and expert in light pollution, collaborated with an international team, led by...

Imagine descending in a submarine to the ice-cold, ink-black depths of the ocean, 800 meters under the surface of the Atlantic. Here the tops of the hills are covered in large coral reefs. NIOZ-researcher Furu Mienis studied the formation of these unknown cold-water relatives of the better-known tropical corals. Furu Mienis studied the development of carbonate mounds dominated by cold-water corals in the Atlantic Ocean at depths of six hundred to a thousand meters. These reefs can be found...

The U.S. Fisheries Service says it will increase its protection of elkhorn and staghorn corals in Florida, Puerto Rico and the U.S. Virgin Islands. The service, part of the National Oceanic and Atmospheric Administration, says new regulations prohibiting activities that result in death or harm to either of the threatened species become effective Nov. 21. "These corals were once the major reef builders in Florida and the Caribbean, but now more than 90 percent of their populations are...

New research in Australia has found disturbing new evidence to show that the world's coral reefs may be in more immediate danger than some experts previously considered. Australian scientists studied the effects of climate change and rising sea temperatures to find that these events may speed the process of coral bleaching, thus leading to the destruction of the world's reefs. "Previous predictions of coral bleaching have been far too conservative, because they didn't factor in the effect of...

Rare corals may be smarter than we thought. Faced with a dire shortage of mates of their own kind, new research suggests they may be able to cross-breed with certain other coral species to breed themselves out of a one-way trip to extinction. This finding, released by scientists at the ARC Centre of Excellence for Coral Reef Studies, has raised hopes for the ability of the world's corals to withstand the rigors of changing climates and human impacts, says lead author Zoe Richards. "Coral...

Coral reefs are submerged structures consisting of calcium carbonate secreted by corals. Coral reefs are colonies of small animals found in marine waters that enclose few nutrients. The majority of coral reefs are constructed from stony corals, which then consist of polyps that come together in groups. The polyps are like small sea anemones, to which they are very closely related. Unlike the sea anemones, coral polyps secrete hard carbonate exoskeletons which provide support and protections...

Chalice Corals, are a family of stony corals in the Pectiniidae family. Members of this family are mostly colonial but at least one species, Echinomorpha nishihirai, is solitary. These corals are endemic to the Indian and Pacific oceans. Pectiniids have a number of different forms but are basically streamlined and smooth. Polyps are large and brightly colored and resemble those of members of the Mussidae family of corals. The polyps are only extended at night. Tentacles are translucent,...

Siderastreidae is a family of colonial, reef building stony corals. Members of this family include symbiotic algae in their tissues which help provide their energy requirements. The World Register of Marine Species lists 7 genera within this family: Anomastraea, Coscinaraea, Craterastrea, Horastrea, Psammocora, Pseudosiderastrea, and Siderastrea. Corals in this family vary in form and include massive, thickly encrusting, columnar, and irregular forms. Corallites are linked by flowing...

Horn corals, known as Rugosa or Tetracoralla, are an extinct order of coral that were abundant during the Middle Ordovician to Late Permian stages. They were known as horn corals because of a unique horn-shaped chamber with a wrinkled (rugose) wall. These mostly solitary corals often reached lengths of nearly 40 inches. However, some species could form large colonies. Rugose corals have a skeleton made up of calcite that is often fossilized. Like modern corals, rugose corals were...

Tabulata is a family of extinct tabulate corals. These corals lived entirely during the Paleozoic era, being found from the Ordovician to the Permian stages. There are about 300 known genera of tabulate corals, of which Aulopora, Favosites, Halysites, Heliolites, Pleurodictyum, Sarcinula and Syringopora are the most common in the fossil record. These corals were mostly found in the shallow waters of the Silurian and Devonian, after which, they became much less common. They became extinct...

  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
